Capacitive Humidity Sensor to Analog Output Converter

https://www.electronics-lab.com/project/capacitive-humidity-sensor-to-analog-output-converter/

The project presented here is an analog capacitive humidity sensor converter board suitable for various humidity measurement tasks. The circuit comes from Texas Instruments application note (see below). Most conventional capacitive proximity sensors produce a digital signal, but this circuit produces a DC output voltage that is a function of the relative humidity of the […]
